MOISTURE-SUPPLYING ATTACHMENT FOR CARJBURET(JRS.`

Application led February 23, 1924.

This invention relates to moisture supplying attachments yforcarburetors of internal combustion engines.

An object of the invention is to provide an attachment for carburetorsof internal combustion engines, which is adapted to supply moisture tothe air in the intake manifold which is broken up into finely dividedform or vapor and interinixed with the vaporizcd fuel in the carburetoror supplied to the internal combustion engine.

Another object of the invention resides in providing a fitting adaptedfor removable attachment in the air intake of a carburetor having awater container connected therewith, and provided with air intakeopenings sothat the suction of the engine will draw air through thewater container and the fitting into the carburetor and in drawing thisair therethrough will operate to take up moisture from the tank which isevaporated and broken up into finely divided form and intermingled withthe vaporized fuel as it passes through the carburetor.

The invention includes other objects and improvements in the details ofconstruction and arrangement of the parts for attachment to a carburetorwhich is more particu larly pointed out in the following description andclaim directed to a preferred form of the invention, it being understoodhowever, that variations in this construction may be made withoutdeparting from the spirit and scope of the appended claim.

Tn the drawing, forming a part of this application rllhe figureillustrates a vertical sectional view through the water container and apor-- tion of the fitting for the carburetor.

1 indicates a tubular fitting of angular form, provided with a flangedportion 2 adjacent one end thereof, which end is adapted to be insertedin the air intake of the carburetor of the internal combustion engine.

The other end of the fitting is extended upwardly as shown in thedrawing and receives the lower end portion of a tank or casing 3 ofcylindrical form, and which is mounted concentrically on the upwardlyeX- tending end of the fitting 1, the tank being provided with anopening t in the lower end thereof to receive the fitting, and ahorizontal perforated partition wall 5 having a Serial No. 694,794.

central opening into which the upper end of the fitting is secured, theperforated partition wall and the bottom wall of the casing` or tanksecuring said tank on the litting.

An overflow pipe is indicated at 6, and has its lower end formed with areturn bend T, which extends through the bottom wall of the tank 3. theupper end of the overflow pipe terminating below the horizontal plane ofthe perforated partition wall 5 and 65 being designed for determiningthe water level within the tank, which must be maintained below thepartition wall 5, so that in filling the tank, it can be readilyascertained when the proper level of water is reached in the tank byexamining the overflow pipe. The upper end of the tank is closed by thetop wall 8, which is provided with a hanger extension 9 adapted toibeattached to a suitable portion of the engine to properly support thetank in au upright position as shown in the drawing, the top wall 8 alsoforming a support for the filler tube 10, which extends downwardlythrough the tank and the partition wall 5, and is provided with a funnellike mouth 11 at the upper end, in order that the water may be pouredinto the filler tube for 'Killing the tank. A valve 12 is provided att-he upper end of the filler tube for closing the passage therethrough.

The upper end portion of the tank 3 .is provided with a plurality of airinlet openings 13 arranged in spaced relation around the entire upperend of the tank, and a water conducting` tube 111 is mounted in thepartition walls 5 and has one end extended downwardly in the casing to apoint adjacent the bottom thereof, while the other end is formed with areturn bend 15, the end portion of which extends downwardly in the upperend of the tubular fitting 1.

lhen the fitting lis properly attached to the air intake of acarburetor, and the engine thereof is operating, the suction in theintake manifold serves to draw air through the openings 13 anddownwardly into the tubular fitting 1, which suction will act throughthe water conveying pipe 14 for sucking water therethrough to be 105dropped into the tubular fitting 1, the water being broken up intofinely divided form and vaporized by the air as it leaves the end of thewater supply pipe 14, so that it will ntermingle with the vaporized gaswhen it reaches the eznflnu'etor 'for :L Subsequent conveyance throughthe intake manifold into the engine.

It, will be clear from the above description, therefore, that aconvenient and novel attachment hns been provided for carburetors,adapted to cont-tin moisture for supply to the engine, which may bemanufactured :it n relatively small cost by reason ot its simplicity ofstructure.

lli/That claimed is:

il, moisture Supplying nttnehnlent for enrburetors ot internalCombustion engines including nn elbow fitting haring one end normallypositioned in :in upright position :1nd the other enfl :nlnptetl 'foruttzielnnent to the intuke oi :i Carburetor` n cylindrical tank mountedon the upwardly projecting),v enfl of seid litting' and having the endterminating in the central portion of the tank,

u partition well provided with n, plurality of perforetions mounted inthe tank and on the fitting below the upper end thereof, the upper endof said tzrnk being formed with :i plurality of air inlet openings, anoverflow for the tank tor maintaining the Wnter level below theperforated partition, filler ineens for the tank, and a Water Cleliverypipe mounted in the partition Wall :and extending' in close proximityWith the bottom of the tank having the other end `lorn'ietl with n.returned end extending into .esiiil lifting', whereby air being suckedtlirougzh the trink intl the fitting will drew :i i'n'etletermined:miount of' Water through Suirl water delivery pipe into the fitting.

ln testimony whereof I nl'ix my signuture.
